Hi,
would you recommend them for 80$?

Honestly, for just slightly more money, a much better option would be the Philips SHP9500 bundled with the V-Moda Boom Pro mic. As of this moment, they are $74.95 for the headphones, and $29.50 for the mic on Amazon.
 
The wideness of the soundstage on the PC350SE really is spectacular. In all other areas of sound reproduction, they fail horribly however....or at least my particular pair does.

Unfortunately i could not find a good offer for the Philips here in Europe (120$ without counting the shipping to where i live).
I can return the Senn if i'm not happy with them, so i'll get them.
Thanks for the advice anyway.
